高考英语复习备考：阅读理解中信息定位的八个技巧
我们知道，任何一道阅读题，无论深浅难易，在文中一定能到依据。解题时，到依据在文中出现的位置，叫信息定位。考生如能准确定位，正确选项会较为明显，其余选项也几乎不构成干扰，因此，又快又准地进行信息定位非常重要。以下是总结的八个定位技巧。
一、用专有名词定位
因人名、地名、组织机构名等专有名词，首字通常要大写，在文中很容易辨认出来，因此，可利用专有名词在文中迅速定位。如：
[例1]
22. When can you go to a concert by Chamber Orchestra？
A. February. B. May. C. August. D. November.
解题过程：用题干中的专有名词Chamber Orchestra定位，在文中到下列段落：
Chamber Orchestra： The Orchestra plays at Memorial Hall at 1406 Elm Street， which offers several concerts from March through June. Call 723-1182 for more information. http：www.chamberoch.
又因本题是问时间，具体依据为which offers several concerts from March through June；比较各选项，只有选项B符合from March through June，故选B。
二、用主题名词定位
就是用题干中能体现该句主题或中心的名词作为定位词，在文中迅速定位。
[例2]
25. What happened when Welty was with her friends at the cafe？
A. Two strangers joined her.
B. Her childhood friends came in.
C. A heavy rain ruined the dinner.
D. Some people held a party there.
解题过程：本题问Welty和朋友在café餐馆里发生了什么。我们用café作为定位词，在文中到下列段落：
On one of her trips to New York several years ago， Eudora Welty decided to take a couple of New York friends out to dinner. They settled in at a comfortable East Side cafe and within minutes， another customer was approaching their table.
“Hey， arent you from Mississippi？”the elegant， white-haired writer remembered being asked by the stranger. “Im from Mississippi too.”
Without a second thought， the woman joined the Welty party. When her dinner partner showed up， she also pulled up a chair.
“They began telling me all the news of Mississippi，” Welty said. “I didn't know what my New York friends were thinking.”
Taxis on a rainy New York night are rarer than sunshine. By the time the group got up to leave， it was pouring outside. Weltys new friends immediately sent a waiter to find a cab. Heading back downtown toward her hotel， her big city friends were amazed at the turn of events that had changed their Big Apple dinner into a Mississippi state reunion（团聚）.
顺着café往下读，然后对比各选项，可知A项正确。B项和D项无中生有，C项“大雨搞砸了晚餐”与文中By the time the group got up to leave， it was pouring outside.（吃完饭起身要离开时，外面下着大雨）不符。
三、用主题动词定位
就是用题干中能体现该句主题或中心的动词作为定位词，在文中迅速定位。
[例3]
15. Which number should you call if you lose something on the Metro？
A. 202-962-1195 B. 202-962-1100
C. 202-637-7000 D. 202-637-8000
解题过程：本题问如果你在地铁丢失了东西应拨打哪个号码，能体现本句中心思想的应是“丢失”东西，故用lose作为定位词，在文中到：
If you lose something on a bus or train or in a station， please call Lost & Found at 202-962-1195.
将202-962-1195对比各选项，只有选项A正确。
四、用生词难词定位
就是用题干中出现的生词、难词、长词等作为定位词，在文中迅速定位。
[例4]
29. What can we learn about Decio？
A. It is a new variety. B. It has a strange look.
C. It is rarely seen now. D. It has a special taste.
解题过程：题干中Decio这个词是我们不认识的生词（其实也是主题名词、也是大写开头的专有名词），可以将其作为定位词，在文中到：
To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets， it can be quite an eye-opener to see the range of classical apples still in existence， such as Decio which was grown by the Romans. Although it doesn't taste of anything special， its still worth
理解该句“能看到大量经典品种的苹果依然存在，如罗马人曾种植的Decio，确实令人大开眼界”，“依然存在”说明“现在极少见到了”，对比各选项，只有选项C正确。
五、用缩略词定位
因缩略词通常是以大写字母的形式出现，在文中很容易辨认，如果题干中出现了缩略词，我们可将其作为定位词，在文中迅速定位。faster怎么读?
[例5]
23. Where can students go for free performances with their ID cards？
A. Music Hall. B. Memorial Hall.
C. Patricia Cobbett Theater. D. Riverbend Music Theater.
解题过程：用题干中的缩略词ID（是identification或identity的缩略词）作为定位词，在文中迅速到：
College Conservatory of Music（CCM）： Performances are on the main campus（校园）of the university， usually at Patricia Students with ID cards can attend the events for free.
对比各选项，只有选项C正确。
六、用时间数字定位
因表示时间的词或是阿拉伯数字在文中极易辨认，如果题干中出现了表示时间的词或数字，可将其作为定位词。
[例6]
27. What did Crosby say about people in the 1960s？
A. They were unsure of raise more children.
B. They were eager to raise more children.
C. They wanted to live away from their parents.
D. They had little respect for their grandparents.
解題过程：用题干中的1960作为定位词，在文中到：
“In the 1960s we were all a little wild and couldnt get away from home far enough or fast enough to prove we could do it on our own，”says Christine Crosby， publisher of Grate magazine for grandparents.
理解句意“在20世纪60年代，我们都有点轻狂，想离家越远越好，越快越好，来证明我们自己能独立。”对比各选项，只有选项C正确。
七、用特殊符号定位
若题干中有带引号或连字符号的词，可将其作为定位词。
